TYPEWRITER ACCENT-KEY ATTACHMENT.

Application filed November 17, 1919.

To all whom it may concern:

Be it known that I, ALFONSO HERING, a citizen of Chile, South America,and a resident of Brooklyn, in the county of Kings and State'oi' NewYork, have invented cer tain new and useful Improvements in TypewriterAccent-Key Attachments, of which the following is a specification.v

The principal object of this invention is to provide a simple, effectiveand inexpensive attachment for typewriters designed to permit theprinting of accent marks, as used particularly in foreign composition,without the necessity of back spacing or with regard to the position ofthe key carrying the accent type.

Another object is in the provision made for quickly and convenientlyattaching the device to machines of the Underwood type without having todisarrange the parts.

A further object is in the means provided for making connection to anynumber ofkey levers when a plurality of accent marks are desired.

These objects are attained b the novel construction and combinationparts here inafter described, and shown in the accompanying drawings,formin a material part of this disclosure, and in-w ich':-

Figure 1 is a partial sectional and side elevational view of theoperative parts of the machine, showing the intercepting deviceconstituting the invention.

Fig 2 is a similar view of the same in operating position.

Fig. 3 is a rear elevational view of the interceptor, rocker bar andconnections.

Fig. 4: is an end elevational view of the same, and,

Fig. 5 is a perspective view of the interceptor plate and lever.

Referring to the drawings in detail, the numeral designates a typewriterkey lever pivoted at the point 12 and provided with a slot 14., engagedby the hook 15 of the operating pull wire 16, the upper end of which isheld in an opening in the U shaped clamp 17 and prevented from droppingout by an integral hook 18, the clamp 17 being adjustably securedlengthwise of the rocker bar 20 by the bindingscrew 19. V

Rigidly attached to the rocker bar 20, in a relatively central position,is an eye 22 having a rearwardly extending arm 23, turned angularly, asat 24:, parallel to the bar 20,

and pivotally secured upon it, by the lugs Specification of LettersPatent. Patented J an. 18, 1921,

Serial No. 338,519.

25 and 26, is an interceptor 28 in register and contactable with the dogrocker 31 of the machine.

The interceptor 28 is reinforced by extending the lug 26 to its loweredge, and also thickened at the top by a reentrantly turned clip portion29.

he interceptor is held in anormally vertical position, due to itsengagement with the bar :20, by the torsional eifect of the coiledspring 32, secured to the bar at one end and engaged by its hooked end33 with the support 34, the latter being provided with an opening toreceive the rod 20 and at its opposite end with an angular outturnedfoot for securing it to the frame of the machine. A similar support 35is provided to receive the opposite end of the bar 20, which is retainedin position between the supports by the collar 36 and spring 32.

The pivoted interceptor 28 is mounted with the narrow upper portion 29between the universal bar 30 and the dog rocker 31, the escapementadjusting screw 38 being ground flush with the dog rocker on its adjacent side to allow the interceptor to move freely when in contact. a

The lower portion of the interceptor acts as a dog rocker lock, thespring 32 always holding the interceptor in normal position, except whenthe accent keys are depressed, the connecting wire 16, which engages thebar 20, being adjusted to aline with accent key levers 10, and if aplurality of accent keys are required, additional connecting wires andclamps may be placed upon the bar 20 and connections made as described.

The flanged bases or feet of the two supports34 and 35, holding the bar20, are substituted for the original ribbon shaft actuator supportbearing caps by taking out the holding screws and exchanging the parts.

In operation, upon depressing the key, carrying the accent character,the rocking bar 20 is partially rotated by the hooked wire 16 connectingit with the key lever, which action lowers the intercepter, therebypreventing the carriage from moving a space by interposing theinterceptor between the dog rocker and the tie bar 40 of the escapementframe. the downward movement of the interceptor being limited by theadjusting make contact with the interceptor and through it tilt the dogrocker, but when the interceptor is lowered, by action of the acccentkey lever, as shown in Fig. 2, the universal bar cannot reach the dogrocker, the screw point having been removed, thus rendering theescapement temporarily inoperative.

Having thus described my invention, what "I claim as new and desire tosecure by Let ters Patent, is

1. A non-feed accent key attachment comprising in combination with atypewriter having a 'tie bar, a universal bar, an escapement, includinga dog rocker carrying a rigid and loose dog, accent type bars, and keysfor operation thereof, of an interceptor adapted to make contact withsaid dog rocker, and means engaged with one or more of said accent typebars for moving said interceptor into the path of motion of said dogrocker relative to said tie bar whereby it is prevented from operationand coincident-1y out of the path of travel of said universal bar. r

' 2. Anon-feed accent key attachment comprisingin 'combination with atypewriter having an escapement including a dog rocker carrying a rigidand a loose dog, accent type bars, operating keys, a tie bar adjacentsaid escapement and a universal bar, of an interceptor interposedbetween said dog rocker and universal bar when transmitting motion tothe dog'rocker, and means integral with said interceptor actuated bysaid accent type bars for retracting said interceptor when said'bars aredepressed and for blocking said dog rocker against said tie bar.

3. A non-feed accent key attachment comprising, in combination with atypewriting machine having a tie bar, an oscillating dogrocker and keyoperated mechanism for imprinting accents, of a rock-shaft supportedtransversely in said machine, operative connections between saidrock-shaft and said key mechanism whereby the rock-shalt may bepartially rotated, means for returning said rock-shaft to its normalposition upon the release of said key mechanism. and an interceptoractuated by said rock-shaft. said interceptor being adapted topositively pre vent the normal movement o1? said dogrocker when saidrock-shaft is moved by said accent printing mechanism by intereeptin rbetween the lower portion of said dog rocker and said tie bar.

*1. A. non-feed accentkey attachment comprising in combination with atypewriting machine having 'an oscillating dog rocker carrying a rigidand a loose dog, and a key actuated mechanism for printing accents. o t'a rock-shaft, arranged transversely in said machine, supports for saidshalt attached rigidly to said machine, a torsional spring fixedrespectively to said shaft and to one of said supports, clampsadjustable longitudinally on said shaft, links engaging said clamps andthe accent key levers, an eve rigid on said shaft, an arm formed withsaid eye, said arm having an angular outer end. an interceptor platepivoted on said angular end, and reinforcements formed on saidinterceptor plate, said plate being adapted to move into contact withsaid dog rocker and prevent it from operating upon the depres sion ofsaid accent key levers.

In testimony whereof I have. signed my name to this specification.

ALFONSO HERENH.
